AION 2 Patch Notes — September 24, 2026 (Emergency Maintenance)
A one-hour overnight maintenance aimed at server load during the Abyss evening. The Dimensional Core siege and boss spawns are now staggered 10 minutes apart between matching-server groups instead of 5, which splits the Abyss schedule into 22:00, 22:10 and 22:20 groups of seven matched server pairs each. A Special Daeva Supply Chest was paid as compensation. Translated from the official Korean notice.
